pi-tui

pi-tui is a skill for Claude Code from romiluz13/pi-agent-skills. It costs 84 tokens per session (460 once invoked), scanned A, original, MIT.

A minimal terminal user-interface library for building interactive text screens, including components such as editors, markdown views, and selection lists. It updates only changed screen areas and supports synchronized terminal output and keyboard input.

In plain words
What is it for?
Use it when building or debugging terminal interfaces, custom components, overlays, text input, keyboard shortcuts, markdown display, or selection controls.
Why use it?
It provides rules that help prevent flicker, broken layouts, incorrect text widths, and cursor problems in terminal applications. Components must keep rendered lines within the available width.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Fable 5.1 $0.00084 $0.00460
Opus 5.5 $0.00034 $0.00184

Security

Grade A, and why

pi-tui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Pi TUI library (@mariozechner/pi-tui)

Grounding

  1. pi-mono/packages/tui/README.md — core TUI concepts, Overlays, Component interface, Focusable IME, Built-in Components, and Differential Rendering.
  2. pi-mono/packages/coding-agent/docs/tui.md — agent-specific TUI component usage (if applicable).
  3. pi-mono/packages/tui/src/ — read specific component implementations when needing deeper context.

Invariants

  • Synchronized Output: Uses CSI 2026 for atomic screen updates. Do not attempt to bypass differential rendering with raw console.log when the TUI is active.
  • Component Interface: Each line returned by render(width) MUST NOT exceed the width parameter; use truncateToWidth or wrapTextWithAnsi.
  • IME Support: Components needing text input (cursors) must implement the Focusable interface to position the hardware cursor correctly.

Workflows

  • Custom Component: Implement Component interface (render, handleInput, invalidate). Check width constraints explicitly.
  • Overlays: Use tui.showOverlay(component, options) for floating UI elements like dialogs, menus, or alerts.
  • Key Detection: Use matchesKey(data, Key.xxx) for keyboard input detection instead of manual string matching.

Anti-patterns

  • Do not use generic string length for text formatting; always use visibleWidth and truncateToWidth to account for ANSI escape codes properly.
  • Do not clear the screen manually; let the differential rendering strategies handle updates.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
